About this app

Calm Ball is a simple bilateral stimulation timer for everyday calming, focus, and wind-down. Follow a smooth ball with your eyes, follow the breathing circle, or do both at once, while gentle tones alternate left and right in your headphones — the same kind of steady left-right rhythm people call bilateral stimulation, or BLS.

No account. No analytics. Your sessions never leave your device. Works offline. One-time purchase, never a subscription.

HOW IT WORKS
Pick a session type — bouncing ball, breathing guide, or both — then a motion, a speed, and a length, and press start. The ball moves side to side (or up-down, diagonal, figure-8, or circle) while soft stereo tones and gentle haptic pulses alternate with it; in breathing sessions a soft peep marks each breath phase. Pause anytime; longer sessions stop automatically.

FOR CALM MOMENTS
- SOS calm: one-tap 3-minute session with a guided 5-4-3-2-1 grounding walkthrough (see, hear, touch, smell, taste)
- Safe place: a 5-minute slow-breathing session (box breathing and 4-7-8)

EVERYTHING ADJUSTABLE
- Speed 0.2-2.0 Hz, sessions from 1 minute to 60 minutes plus open-ended timers
- 6 bilateral tones plus silent, volume control, and a swap left/right option for flipped headsets
- Haptics, reduce-motion mode, 3 ball sizes, accent themes, and dark mode
- Full-screen and sideways (landscape) mode for wider ball travel
- Mid-session control sheet: change tone, speed, or volume without restarting
- Save your favorite setups as one-tap presets

TRACK YOUR ROUTINE
- Session history, streaks, daily minute goals, and a weekly chart
- Optional 1-5 calm check-in after each session, saved presets, and shareable summaries

MADE FOR REAL LIFE
- Headphones recommended for the stereo tones; haptics let you close your eyes
- Great for a two-minute reset between meetings, a longer wind-down at night, or focus before a task
- Simple enough to use when you are stressed, calm enough not to add to it
